A system and method for detecting dust (18) on an image sensor (20) from a single captured image (14) of an actual scene (12) includes a control system (22) that evaluates at least one of a hue channel (466), a value channel (470), and a saturation channel (468) of the captured image (14) to determine if there is dust (18) on the image sensor (20). For example, the control system (22) can evaluate the hue channel (466) and the value channel (470) of the captured image (14) to determine if there is dust (18) on the image sensor (20). With information from the hue channel (466) and the value channel (470), the control system (22) can compute a computed probability (572) of dust (18) for a plurality of pixels (362) of the captured image (14). |
